That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Wilton
Your AC runs hard from May through October in Wilton, pushing cooled air through ductwork that may be leaking 20-30% of it into your attic or crawlspace before it ever reaches your living room. That’s not an equipment problem; it’s a sealing problem, and it’s costing you every month on your SMUD bill. We’re Hollis Air Duct Cleaning, and our Duct Sealing crews serve Wilton from our Sacramento dispatch office, typically arriving inside our quoted window to homes along Dillard Road, Twin Cities Road, and the acreage lots off Grant Line. Call us at (361) 326-5060 for a free estimate, or read on to understand what sealing actually involves and what it costs in Wilton’s market.
Why Hollis Air Duct Cleaning Is Wilton’s Preferred Duct Sealing Company
We’ve been sealing ducts in rural Sacramento County since 2004, and Wilton’s mix of older ranch homes, double-wides, and custom rural builds is familiar territory. Our technicians know the long flex-duct runs common on multi-acre lots here, the rodent damage from field mice nesting in crawlspaces, and the way Delta breeze pressure changes can expose leaks that stay hidden in more sheltered suburban systems.
Our Wilton customers mention the same things in feedback: we show up inside the window, we price in writing before touching anything, and we leave the site clean. That’s The Garrison Standard, and it’s how every Hollis location operates, including ours serving Duct Sealing in Wilton.
Roy Castellanos leads this operation, and our 365-Day Done Right Promise applies to every sealing job we do in Wilton. If the mastic fails, the tape lifts, or a leak reopens within a full year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule.
Duct Sealing Services in Wilton
Duct Sealing Services in Wilton address the leaks, gaps, and disconnected joints that waste cooled air in your attic or crawlspace during our brutal Central Valley summers. A typical whole-system seal in Wilton runs $850 – $1,400 for a standard single-family home, depending on accessibility, duct material, and the extent of damage from rodents or age-related deterioration. We also handle Air Duct Cleaning in Wilton and Dryer Vent Cleaning in Wilton for homeowners who want their full system addressed in one visit.
Mastic Sealing for Leaking Joints
We brush on UL-181 rated duct mastic at every connection point, boot, and plenum seam. Unlike tape alone, mastic remains flexible through Wilton’s temperature swings and won’t dry out and crack after a single summer. Our crews use Nikro negative-air equipment to pressurize the system during application, ensuring the sealant gets drawn into hairline gaps you’d never spot by eye.
Metal Tape and Mechanical Repair
Where flex duct has pulled away from collars or rodents have chewed access holes, we install new mechanical connections wrapped with foil-backed tape rated for permanent HVAC use. This isn’t the hardware-store duct tape that peels in heat; it’s the same tape commercial crews use on Abatement Technologies systems, and it’s what we specify for every Wilton job.

Duct Insulation in Wilton
Duct Insulation in Wilton protects the air you’ve already paid to cool from the 140°F+ temperatures common in unvented attics during July and August. Even perfectly sealed ducts lose efficiency fast when they’re bare metal or thin flex running through a bake-oven attic space. A typical insulation wrap or replacement in Wilton runs $600 – $1,100, with full duct replacement and insulation upgrade reaching $2,000 – $3,500 for larger rural homes with extended runs.
R-Value Upgrades for Attic Runs
We wrap existing sealed ducts with R-6 or R-8 insulation, securing it with mechanical fasteners so it won’t sag or compress over time. In Wilton’s extended AC season, every degree of temperature preserved in the duct line is a degree your compressor doesn’t have to work to replace. Our technicians use Guardsman-rated insulation products specified for California Title 24 compliance.
Crawlspace Condensation Control
Homes near the Cosumnes River corridor and lower-lying Wilton parcels see higher winter groundwater and crawlspace humidity. Insulated ducts prevent the surface sweating that leads to mold, mildew smell, and deterioration of surrounding framing. We inspect for this condition on every sealing job and recommend insulation upgrades where we find it.
Trusted Brands We Service in Wilton
Our vans carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration and insulation products from Honeywell, Aprilaire, and Guardsman. We stock common sealing materials and insulation wraps locally, so most Wilton jobs don’t wait on parts. When we encounter a system requiring specialized components, our Sacramento office coordinates same-day or next-morning pickup. You’re not getting hardware-store tape and crossed fingers; you’re getting the same tools and materials that commercial HVAC contractors specify for hospitals and schools, applied to your home by background-checked, uniformed technicians who work under The Garrison Code.
Common Duct Sealing Problems We See in Wilton Homes
- Rodent-damaged flex duct on acreage lots. Field mice and roof rats from surrounding farmland nest in Wilton’s crawlspaces and attics, chewing through flex duct to access nesting material and creating leaks that spray conditioned air into uninhabited spaces. We find this on roughly half the rural Wilton homes we inspect, and we seal with rodent-resistant materials after cleaning.
- Disconnected collars in older ranch construction. The ranch homes built along Dillard Road and Grant Line in the 1960s – 1980s often used snap-together duct connections that loosen over decades of thermal expansion. We reconnect with permanent mechanical fasteners and mastic, not temporary fixes.
- Long flex-duct runs sagging between supports. Wilton’s custom rural builds frequently run 40 – 60 feet of flex duct to reach distant rooms, and inadequate support spacing creates low points where dust, pollen, and condensation collect. We add supports and seal the resulting joint stress.
- Wildfire smoke infiltration through attic leaks. During foothill fire season, pressure differentials pull smoke through unsealed ductwork in attic installations. Proper sealing with mastic and tape creates a barrier that keeps your indoor air separate from whatever’s burning outside.

Yes, we seal ducts throughout Wilton, from the compact homes near the Wilton Elementary School area to the multi-acre parcels along Dillard Road, Twin Cities Road, and the Grant Line corridor. Our trucks carry ladders and crawlspace gear sized for rural access.
We prioritize calls where a complete duct separation has disabled cooling during heat over 95°F, or where wildfire smoke is actively entering through attic duct leaks.

Wilton pricing runs comparable to Elk Grove and slightly below Rancho Cordova for equivalent homes. The variable is access: rural Wilton homes with crawlspace installations and long duct runs take more time than compact suburban systems, which can push some jobs toward the higher end of our ranges. We price each home individually after inspection.
